MIXIN G-MAGHINE.

Specification of Letters Patent.

Patented Feb. 2, 1915'.

Application filed November 23, 1914. Serial No. 873,586.

To all whom it may concern:

Be it known that I, Josnrrr F. PRoKoP, a citizen of the United States,residing at Hay Springs, in the county of Sheridan and State ofNebraska, have invented certain new and useful Improvements in Mixing-Machines, of which the following is a specification, reference being hadto the accompanying drawings.

This invention relates to certain improvell'lQIliS in mixing machinesand has relation more particularly to a device of this general characterespecially designed and adapted for use in the mixing of concrete andthe like; and the object of the invention is to provide a novel andimproved machine of this general character wherein the mixing elementcontinuously rotates during the mixing operation and at the time thesame is being emptied.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved mixingmachine whereby certain important advantages are attained and the deviceis rendered simpler, less expensive and otherwise more convenient andadvantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully defined in theappended claim.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein- Figure 1 is a view in top plan of a mixing machineconstructed in accordance with an embodiment of my invention; Fig. 2 isa sectional view taken substantially on the line 2-2 of Fig. 1; and Fig.3 is a frag mentary elevational view of the upper extremity of anupright, herein included, and illustrating in detail one of the bearingscarried thereby.

As disclosed in the accompanying drawings, 1 denotes a suitablysupported frame having disposed transversely thereacross adjacent oneextremity the shaft 2 adapted to he operatively connected, as at 3, in aconventional way with the motor 4: also operatively supported by theframe 1 but preferably adjacent the opposite end thereof. Projectinglaterally from the frame 1 adjacent the end thereof provided with theshaft 2 is a supplemental frame 5 provided at its outer extremity withthe upright 6 provided adjacent its opposite extremities with thebearings 7, one of said bearings being disposed a predetermined distancebelow the horizontal planeof the shaft 2, for a purpose which isbelieved to be self-evident.

Operatively engaged with the shaft 2 through the medium of a universaljoint 8 is an elongated shaft section 9, one extremity whereof beingadapted to be supported by one of the bearings 7, said bearings be ingherein disclosed as substantially hookshape in form so that the shaftsection 9 may be readily applied or removed therefrom, for a purposewhich will be self-evident. The shaft section 9 is disposed through themixing element 10, herein disclosed as in the form of a barrel andhaving its lower end closed while its opposite or open end isintersected by the spider 11 suitably afiixed to the shaft section 9.The closed end 12 of the mixing element is also fixed to the shaftsection 9 whereby it will be perceived that such element will be causedto rotate with the section 9. With the shaft section 9 engaged with theupper bearing 7 it will be perceived that the ingredients to be mixedmay be readily deposited within the mixing element through the open facethereof, while the same will be readily discharged from the mixingelement when the shaft section 9 is caused to engage with the lowerbearing 7, it being understood that such lower bearing is positioned asuflicient distance below the shaft 2 as to dispose the mixing elementon such an inclination as to permit the axial rotation thereof tofacilitate the discharge of its contents.

lVhile any means may be employed for supporting the frame 1, I find itof advantage to use conventional wheels 1d whereby the apparatus may beof a portable type and be conveyed from one point to another withconvenience and facility as the requirements of practice maynecessitate.

From the foregoing description, it is thought to be obvious that amixing machine constructed in accordance with my inven tion is of anextremely simple and comparatively inexpensive nature and isparticularly well adapted for use by reason of the convenience andfacility with which it may be assembled, and it will also be obviousthat my invention is susceptible of some change and modification withoutmaterial departure from the principles and spirit thereof and for thisreason I do not Wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein. shown in carryingout my invention in practice.

I claim:

A device of the character described comprising a support, a frameprojecting laterally from the support, an upright carried by the outerextremity of the lateral frame, said upright extending above and belowthe support, open bearings carried by the opposite extremities of thesupport, a rotatable mixing element including a flexible shaftoperatively engaged with the support, said shaft being adapted fordetachableengagement with the bearings of the upright of the frame, andmeans for imparting axial rotation to the flexible shaft.

In testimony whereof I hereunto aflix my signature in the presence oftwo Witnesses.
